Foreign priority is claimed to this application and a certified copy of the Australian Plant Breeder's Rights application is filed concurrently with the instant application.

The Inventor and Applicant/Assignee assert that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor and/or Applicant/Assignee. Inventor and Applicant/Assignee claim a prior art exemption under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date of this application.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Armeria plant, commonly referred to as Thrift or Sea Pink, botanically known as Armeria pseudarmeria, commercially used as a garden plant, and hereinafter referred to by the name ‘Dream Clouds’.

The new Armeria plant is a product of a planned breeding program in Wonga Park, Victoria, Australia. The objective of the breeding program is to create new Armeria plants with uniform upright plant habit, relatively short flowering stems, medium-sized globular inflorescences and good garden performance.

The new Armeria plant originated from a cross-pollination conducted by the Inventor in Wonga Park, Victoria, Australia in 2012 of a proprietary selection of Armeria pseudarmeria identified as code number IB109-1, not patented, as the female, or seed, parent with Armeria pseudarmeria ‘Sweet Dreams’, disclosed in U.S. Plant Pat. No. 29,612, as the male, or seed, parent. The new Armeria plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination grown in a controlled greenhouse environment in Wonga Park, Victoria, Australia in February, 2013.

Asexual reproduction of the new Armeria plant since 2014 by vegetative cuttings in a controlled environment in Wonga Park, Victoria, Australia has shown that the unique features of this new Armeria plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Armeria have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Dream Clouds’. These characteristics in combination distinguish ‘Dream Clouds’ as a new and distinct Armeria plant:

-   -   1. Relatively short, upright and uniformly mounded plant habit.     -   2. Narrow leaves.     -   3. Freely flowering habit.     -   4. Medium-sized inflorescences positioned on relatively short         peduncles with white-colored flowers.     -   5. Good garden performance.

Plants of the new Armeria can be compared to plants of the female parent selection. Plants of the new Armeria differ primarily from plants of the female parent selection in plant size as plants of the new Armeria have shorter peduncles than plants of the female parent selection. In addition, plants of the new Armeria have narrower leaves than plants of the female parent selection.

Plants of the new Armeria can be compared to plants of the male parent, ‘Sweet Dreams’. Plants of the new Armeria differ primarily from plants of ‘Sweet Dreams’ in flower color as plants of the new Armeria have white-colored flowers whereas plants of ‘Sweet Dreams’ have light purple-colored flowers.

Plants of the new Armeria can be compared to plants of Armeria pseudarmeria ‘Daydream’, disclosed in U.S. Plant Pat. No. 29,381. Plants of the new Armeria differ primarily from plants of ‘Daydream’ in flower color as plants of the new Armeria have white-colored flowers whereas plants of ‘Daydream’ have medium purplish pink-colored flowers.

Plants of the new Armeria can also be compared to plants of Armeria pseudarmeria ‘Ballerina White’, not patented. In side-by-side comparisons, plants of the new Armeria differ primarily from plants of ‘Ballerina White’ in peduncle length and strength as plants of the new Armeria have shorter and stronger peduncles than plants of ‘Ballerina White’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Armeria plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Armeria plant.

The photograph on the first sheet (FIG. 1) is a side perspective view of a typical flowering plant of ‘Dream Clouds’ grown in a container.

The photograph on the second sheet (FIG. 2) is a close-up view of a typical flowering plant of ‘Dream Clouds’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Armeria grown during the spring in one-gallon containers in a glass-covered greenhouse in Elburn, Ill. and an outdoor nursery in Fort Worth, Tex. Plants were grown under cultural practices typical of Armeria production. During the production of the plants, day temperatures averaged 7° C., night temperatures averaged 2° C. and light levels averaged 3,000 foot-candles. Plants were 26 weeks old when the photographs and description were taken. Color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
